Poor Alonso. I would love to see Hamilton and him racing on equal footing.

A fox in Chernobyl has made a large sandwich using cold meats and bread fed to him by a radio crew in the area.

► heat, cooling & radiators
► airflow optimisation

08:40 - Test or Working Section
► test section, settling chamber
► closed-jet, slotted-wall, 3/4 open-jet
► contoured-wall, adaptive-wall

Best use of a 5-second YouTube ad I've ever seen.

You actually get rewarded for watching the whole thing XD

Comes prepared and ready to use. Geneva Artists' Oil Color have already been mixed with Geneva Medium to just the right consistency, so there is no need to thin it down further before using it. And because every pigment is different, they have each been developed with their own unique medium ...
